Davis-Thompson Foundation Workshop – Racehorse necropsy to fulfill Horseracing Integrity and Safety Authority (HISA) requirements

California Animal Health and Food Safety Laboratory, San Bernardino Branch, UC-Davis. 105 W Central Ave, San Bernardino, CA 92408

August 18 @ 8:00 am August 19 @ 5:00 pm San Bernardino – California

Join the CAHFS team in person for a workshop covering Racehorse necropsy to fulfill Horseracing Integrity and Safety Authority (HISA) requirements.

The Horseracing Integrity and Safety Authority (HISA) established uniform, national rules of racing that include, as of July 1, 2022, a requirement that all horses that die at a racetrack under the jurisdiction of HISA (racetracks that conduct interstate wagering) must undergo a necropsy examination. The goals of the examination, essential components of the examination with respect to the etiopathogenesis of racehorse injuries and sudden death, laboratory demonstration of typical racehorse findings, and the standardized HISA necropsy reporting form will be covered in the workshop.

Faculty and support staff:

  • Sue Stover
  • Francisco Uzal
  • Carlos Schild
  • Javier Asin
  • Akinyi Nyaoke
  • Eileen Henderson
